Setting up SATA HD and CD ROM - How to connect ide cable for CD-ROM

[oddvark]

Hey,

I got my first SATA HD setup going. I plugged the HD to the SATA but
how should I connect the CD-ROM?.

1. Is an SATA HD still considered primary master (its my boot drive)?
2. If the CD-ROM is Secondary Master, should I plug it into the END or
MIDDLE of the IDE CABLE.
3. Should I use a 40 or 80 wire cable for the CD-ROM?
4. What confirguration would you recommend? I'm thinging HD = primary
master, cd = secondary master.

Thanks.

I would also add, that I advertantly booted the setup with the CD ROM
in cable select mode. Whats the likely hood of this damaging my
setup???

There is some info on IDE cabling here (uses a popup advert):

http://www.pcguide.com/ref/hdd/if/ide/confCS-c.html

The SATA ports are considered electrically independent of the
IDE ports. You cannot have an electrical fight between whatever
is on a SATA cable and an IDE cable. But do read the section
in the manual, about the BIOS and the drive interfaces, because
there are some settings that can cause some of the drives to be
invisible to the OS install. Intel chipsets have a "Compatible"
mode, that only allows four drives to appear to the OS, and that
is done so you can run an OS like Win98SE. Win98SE only expects
to find four drives, at well known I/O addresses. If you have
some other chipset, they may not offer the ability to install
an older OS, and the visibility issue of drives is simpler.

Currently, the SATA drive on each cable is considered the
"Master", but there is generally no jumpering that you need
to set, that has anything to do with Master and Slave. There
can be jumpers for "Spread Spectrum" and "3Gb/s" versus "1.5Gb/s",
but for the most part, the drives are plug and play. A good
drive should ship from the factory, ready to go with the
lowest common denominator 1.5Gb/sec cable speed. If both
the SATA drive and the motherboard support 3Gb/sec, it might
take some fiddling to get them working at that speed (not that
it particularly matters at the moment).

A day will come in the future, when multiple disk drives can
be hosted off one SATA cable, but AFAIK, that technology isn't
available at retail yet (at least I haven't seen any).

If you only had a single drive on an IDE cable, there is nothing
for it to fight with. I would not expect to find any damage,
and in any case, if you have an 80 wire cable that supports
cable select, you could use that if you wanted. A modern
CDROM should have a cable select option, and I believe I've
used CS on a CDROM and hard drive sharing an 80 wire cable.
If you have some mouldly equipment from the dark ages, maybe
some other rules apply. Modern drives do play nice with one
another.

oddvark:
1. Simply stated, the Primary/Secondary Master/Slave settings do not apply
to SATA HDs as they do to PATA HDs. So forget those designations when a SATA
HD is involved.
2. If you connect your CD-ROM as Secondary Master and that device is the
*only* device on its IDE cable, it's best to connect it to the end connector
of the cable although there's generally no harm in connecting it to the
middle connector. However, if you jumper the device as Cable Select, then
the device's position on the cable is important if there's another device on
the same IDE cable and you want the optical drive as Master (and the other
device as Slave). In that situation you *should* connect the optical drive
to the end connector.
3. Let me put it this way. In one of the computer repair shops I worked in,
*all* 40-wire IDE cables we came across went in the junk bin. We used *only*
80-wire IDE cables. The cost between the two is trifling.

As to you final query...
I haven't the foggiest idea of what you're talking about.

Setting for least conflict is:
SATA on sata drive 0 .. and make sure it formats
as the C-drive.
CDROM on 2nd ide port .. not first.
Jumper CDROM as Master .. not CS.
Nothing on first ide port .. OS install expects anything on
the first ide port to be the drive with the boot partition.
That can create a mess in future installs of apps.

The master-slave issue has already been covered in this thread. Basically,
just plug the SATA into the proper SATA connector on the mobo and it should
be ready, if you haven't futzed with the jumpers. Plug the CD-ROM into the
end of an IDE cable and jumper the drive to master. You can use either 40-
or 80-wire IDE cables for optical drives. I believe CS is available only on
80-wire cables. If I am wrong, someone please correct me.

I really wish you would quit spreading this FUD regarding this. The OS will
install on any hard drive you want it to. There are no conflicts with IDE
and SATA if you configure your bios correctly and for everyone except you
that is easy to do. When you install it, XP will list the partitions it sees
and you can select which one you want to use. If you set the boot order
correctly in the bios the machine will boot normally and there will be no
conflicts.

OK. Thanks everybody, but I have an intermittent disappearing CD-ROM
problem.

I have HD in SATA 0. And currently I have CD-ROM in first IDE Master.
However, every once in a while i cant see the CD-ROM at all. Power is
there (it can open and close) but I dont see it in the OS. In the
BIOS, everything is set to AUTO Detect.

I've swapped CD-ROMS with a known CDROM and to problem still occurs.

I wonder if I should attempt to move CD-ROM to second IDE Master as
john mentions. I also hope I didn't fizzle my MB. I dont have the
actual MB type with me, but its an ASUS.

Anyhow, thanks for the help. I've set up a few systems before, but
this one has been a problem. Any clues?

Have you tried replacing the cable? If that doesn't work, try another Molex
(power) connector from the PSU.

Bullshit! I wish you would shut up.

I will, when you quit giving bogus advice. I have three computers all with
SATA hard drives, two with IDE optical drives on the primary IDE channel and
one with an IDE HDD on the primary IDE channel. There are no problems,
conflicts or anything. All boot to the SATA drives with zero issues. It is
really easy, you set the boot order in the bios to 'cd/dvd drive' first and
hard drives after that. Even if you don't specify in the bios which hard
drive is the boot drive, if there is no boot sector on the drive the system
will look at the next available device and boot. It is very simple and never
causes a problem on a properly configured system.
